Improving fermion mass hierarchy in grand gauge–Higgs unification with localized gauge kinetic terms

Maru Nobuhito , Yatagai Yoshiki

… The Standard model (SM) fermions on one of the boundaries and some massive bulk fermions coupling to the SM fermions on the boundary are introduced, so that they respect an SU(5) symmetry structure. … Higgs potential analysis shows that the electroweak symmetry breaking occurs by introducing additional bulk fermions in simplified representations. …

Suppression and control of prethermalization in multicomponent Fermi gases following a quantum quench

Chen-How-Huang , Takasu Yosuke , Takahashi Yoshiro , Cazalilla Miguel A.

… We find that switching on an interaction that breaks the SU(N) symmetry of the initial Hamiltonian, thus allowing for the occurrence of spin-changing collisions, does not necessarily lead to a suppression of prethermalization. … However, the suppression will be most effective in the presence of SU(N)-breaking interactions provided the number of components N≥4 and the initial state contains a population imbalance that breaks the SU(N) symmetry. …

Molecular and cellular basis of left–right asymmetry in vertebrates

HAMADA Hiroshi

… In many vertebrates including mammals, the breaking of L-R symmetry occurs at a structure known as the L-R organizer (LRO) located at the midline of the developing embryo. … This symmetry breaking is followed by transfer of an active form of the signaling molecule Nodal from the LRO to the lateral plate mesoderm (LPM) on the left side, which results in asymmetric expression of Nodal …
